解析：Version 1，碰到横纵坐标相等的点计算曼哈顿距离，并与最短距离比较，如果更短，则更新最短距离的点的索引以及最短距离。

• Version 1

class Solution:
    def nearestValidPoint(self, x: int, y: int, points: List[List[int]]) -> int:
        index = -1
        minimum = float('inf')
        for i, (x1, y1) in enumerate(points):
            if x == x1:
                distance = abs(y - y1)
                if distance < minimum:
                    minimum = distance
                    index = i
            elif y == y1:
                distance = abs(x - x1)
                if distance < minimum:
                    minimum = distance
                    index = i
        return index
